摘要

提出了一种新颖的具有三阶切比雪夫滤波响应的180°混合电路。从耦合谐振器滤波器的理论出发，可以综合出耦合系数和外部质量因子。实验结果验证了该方法的正确性，仿真结果与实测结果吻合较好。与传统的大鼠赛跑耦合器相比，该结构具有缩小80%的尺寸和高频率选择性的滤波功能。

Design of a 180-degree hybrid with Chebyshev filtering response using coupled resonators

A novel 180 ° hybrid with third-order Chebyshev filtering response is proposed in this paper. The coupling coefficients and the external quality factors can be synthesized from the theory of coupled resonator filter. The proposed idea is verified with experimental results, with good agreement between simulation and measurement. Comparing to the conventional rat-race coupler, 80% size reduction and filtering function with high frequency selectivity has been exhibited in the proposed structure.
